I beg to differ, given that they are operating Mirage 5s still, and Mirage 2000 comparatively is a new aircraft, just as capable as their F-16s (if not more actually - BVR). Also doubt those air frames have aged any worse than our F-16s, as they were delivered to them from 1986-1988. They can also easily upgrade them with commonality with their new Rafales given their good ties with the French.
And this is still perhaps a bit early, but you will most likely see the UAE Mirage 2000s ending up in Egypt down the line too.
